The derivative of a function of f at m is given by . +h)f(w) ' a: = 11m \": f ( ) h>0 h provided the limit exists. Use the definition of the derivative to find the derivative of f (1:) = 6:172 + 8:1: + 4. Enter the fully simplified expression for f (m + h) f(1:).Do not factor. Make sure there is a space between variables. ab sin (a) 00 a M 0 f($+h)-f($) El
